"This building opened in 1970 as the HQ of Belgian concrete- production firm CBR. Architect Constantin Brodzki was charged with showing the power of the company’s product. It’s a first-class example of prefabricated architecture: 756 concrete modules, glass included, that were assembled on-site. Snaking channels between each unit take care of rainfall, meaning there’s no need for plastic piping, and a heating system encased in sapele wood veneer beautifully lines the interior of each floor. Today it’s an office and co-working space owned by Fosbury & Sons, following a sensitive renovation in 2018."
